Mar 15, 2017 · Convection-enhanced delivery (CED) is a promising technique that generates a pressure gradient at the tip of an infusion catheter to deliver therapeutics directly through the interstitial spaces of the central nervous system. It addresses and offers solutions to many limitations of conventional techniques, allowing for delivery past the blood–brain barrier in a targeted and safe manner that ...Author: A. M. Mehta, A. M.

Convection-enhanced delivery to brain parenchyma. Accessibility of pharmacological agents from the bloodstream to the CNS meets with a formidable obstacle in the form of the BBB [].There is an absence of direct intracranial administration-only agents that are actively transported through the BBB or that are otherwise permeable through the barrier, which can directly kill tumor cells.Author: Waldemar Debinski, Stephen B Tatter

Convection Enhanced Delivery (CED) is a therapeutic strategy that was developed to facilitate targeted delivery of pharmaceuticals to the brain. The CED procedure involves a minimally invasive surgical exposure of the brain, followed by placement of small diameter catheters directly into the brain tumor. Subsequently, infusion of therapeutics ...

Sonodynamic therapy is a proposed form of treatment using drugs that only become cytotoxic upon exposure to ultrasound. Since ultrasound can be focused into small tissue volumes within the body, this method provides a potential means of localizing treatment and reducing the risk of toxic side-effects elsewhere in the body.

The brain is highly accessible for nutrients and oxygen, however delivery of drugs to malignant brain tumors is a very challenging task. Convection-enhanced delivery (CED) has been designed to overcome some of the difficulties so that pharmacological agents that would not normally cross the BBB can be used for treatment.Author: Waldemar Debinski, Stephen B Tatter

Convection is the heat transfer due to the bulk movement of molecules within fluids such as gases and liquids, including molten rock ().Convection includes sub-mechanisms of advection (directional bulk-flow transfer of heat), and diffusion (non-directional transfer of …

Summary. This is a Phase I study to determine the maximum tolerated dose (MTD) and/or recommended phase II dose of D2C7-IT (D2C7 Immunotoxin) when delivered intratumorally by convection-enhanced delivery (CED) to recurrent World Health Organization (WHO) grade III and IV malignant glioma patients, and/or to determine what dose will be considered in a Phase II trial.

Convection-enhanced delivery: Chemotherapy is delivered to the tumour by a surgically implanted catheter under a pressure gradient to achieve more distribution than with diffusion alone. Limited experiments have been conducted with brain tumors, including one with a DIPG.
